ANALYSIS OF FACTORS INFLUENCING 3D CONCRETE PRINTING ADOPTION FOR HOUSING CONSTRUCTION IN INDONESIA

Abstract

The construction industry is one of the largest industries, yet it is often perceived as slow to embrace advancements. The most common construction method is the cast-in-situ method, which encounters challenges. In response to these challenges, 3D Concrete Printing (3DCP) emerged as a new method of innovation that relies on extrusion and automation. Currently, the application of 3DCP is limited to constructing structural elements in homes and architectural components. 3DCP offers transformative potential with its automation, reduced waste, and precision, yet its adoption in developing countries remains limited. To enhance the implementation of 3DCP in Indonesia, a study was carried out to identify the factors influencing the willingness to adopt 3DCP and assess their level of significance. These influential factors were identified using frameworks such as the Technology Organization Environment (TOE) and the Unified Theory of Acceptance and Use of Technology (UTAUT). The assessment of adoption levels was conducted by engaging with pioneers in 3DCP in Indonesia and contractors associated with the 10 housing development firms in Indonesia who have not yet integrated 3DCP into their practices, and analyzed using a Likert scale. The implementation of housing construction in Indonesia is influenced by 9 factors, and several strategies and recommendations are needed by the government, 3DCP enthusiasts, and academic institutions. These solutions may be adopted as part of the implementation roadmap strategies for further research and implementation in developing countries.
